We are using the Cisco VPN client version 5.0.01.0600 on Vista and have encountered the auto-tuning problem as noted in the Release Notes for Cisco VPN Client, Release 5.0.00 and Release 5.0.01. Does anyone know if the auto-tuning issue is resolved in later versions of the Cisco client (such as version 5.0.04.0300) or if auto-tuning is also a problem on Vista using the AnyConnect VPN client? Thanks
